PIPE-HANGER..

Specification of Letters Patent.

Patented May 7, 1907.

Application filed December 20,1906. Serial No.\i848.791.

To all whom it may concern:

Be it known that I, HENRY C. TABER, a citizen of the United States, residing at Ware, county ofY Hampshire-State of Massachusetts, have invented a certain new and useful Improvement in Pipe'jHangers, of which the following'is a specification, reference bethe accompanying drawin s. j t

/ly. invention has for its object to provide an improved hanger for supporting pipes,

articularly overhead pipes in buildings and 1t consists of a bracket provided with a base or other portion by means of which it may be aflixed to the wall or other contiguous part of the building or object on or in which the pipes are to the length of which governs the distance at which the pipe is to 'be supported from the wall, ceiling or the like and holdersor fingers which project from the shank portion at the n free endthereof, and which encircle or par- -nection 'with the revolution with reference to the tially encircle the pipe to hold the latter securely in place, the said holders being so located with reference to each other that when the hanger is turned with reference to the pipe the pipe may be slipped out from between the curved holders so as to disengage the lpipe from the hanger.

My invention will be clearly understood from the followingdescription taken in conaccoinpanying drawings which forml a Apart thereof and the novel features of the invention are pointed out and clearly defined in the claimsat the close of this specification.

In the drawings, Figure l represents Aa i front view of my improved hanger with a section of pipe shown as placed therein. Fig. 2 is a vertical section on line 22 of Figz 1, showing the pipe in section anda side view of the hanger. Fig. 3 isk a' view looking down from the line 3-3 of Fig. 1. a similar view to that shown Fig. 3 but shows the hangn turned through one-(uarter ine of pipe so as to permit the pipe to be removedtherefrom. Fig. 5 is a cross section on line 5- -5 of Fig. 4, looking toward the right of the line `5-5, and showing the lower part of the hanger in the positiony in' which itmay be pipe. Fig. 6 is a botinengagement therewith. Figs. 7 and 8 are be supported; a shank portionA Figs. inand out between the fingers; that is, they Fig. 4 is of av modifications of my hanger which will be hereinafter more fully described. Fig. 9 is a front view of a modiiied form of hanger einbodying my invention, said hanger being provided with an adjustable shank so that the shank may .be lengthened or shortened,

' and being also provided kwith means for locking the shank in any desired position. Fig. 10 is a side view of the hanger shown Fig. 9,

the pipe in engagement therewith beingY shown in section. Fig. 11 is a detail designed to show more clearly the construction of the adjustable shank. Fig. 12 is a section on line 12-.-12 of Fig. 10.

Referring to the drawings,-1 represents the shank of the hanger, and 2 the base which is provided with screw holes or other suitable means whereby the hanger may be secured tothe ceiling or other support. As shown in the drawings 3 represents the line of the ceiling or wall, and the hanger is represented as secured thereto by screws 4 passing through screw holes in the base 2.

The other end of the shank is provided with curved pi e supporting fingers 6,y 7 which brauch om o posite sides of the shank and are o posite y curved outwardly, downwardly an then inwardly so as to artially encircle the pipe, being curved or ot erwise bent to conform to the sha e of the ipe, said fingers being also in di erent planes from each other, so the pipe may pass between them and the inwardly turned ends may lap past each other when viewed from the direction shown in Fig. 2. Y The fingers are spread suiiicientlyy apart viewed as in 1 and 5, to permit the pipe being passed should be spread apart laterally about equal to the diameter of the pipe.' It is preferable tomake the spread just equal to the diameter of the pipe, but if desired to afford a little more freedom of movement 'they may be of the pipe.

By the use of hangers of the construction described a system of piping may very easily and expeditiously be installed, and when in position the pipe is held securely 'and may be readily removed without uncoupling-the sections. To insert or'remove the ipe it is noty necessary to slide thefpi e end) In installing it the pipe wi l be moved up between tlie'ngers 6, 7 as Shown in Fig. 5, then made with a greater spread than the diameter wise at all.

J i applicableffen/supporting" p`ipiirg''for other'YV by giving the hanger'a quarter turn, it will bring the curved arms around in supporting position, as shown in Figs. 1, 2 and 8, in which position the hanger will then be secured to the ceiling or other support.

When it is desired to remove the pipe, the hanger will be unscrewed from the wall and given a quarter turn in the position shown Figs. 4 and 5, when the pipe may readily be withdrawn without endwise movement of the pipe or the hanger itself may be lifted away from the pipe.

My improved hanger is especially intended for use in supporting the piping of overhead sprinkler systems, such as are. installed in shops, factories and other buildings, as a pro- 'tection against fire, but it is obvious thatit is purposes. In Figs. 7 and 8 the invention is shown as applied to a wall support, the shank in this instance being made shorter than in Figs. 1 and 2, but is otherwise constructed substantiallyas shown in Figs. 1 to 6 inclusive.

ln Figs. 9 to 12 l have shown a modied form of vhanger embodying my invention. This form is characterized chieiiy by the adjustability of the shank portion, the free end of the hanger, that is the portion upon 3o which is secured the curved holders, is provided with a threaded opening lengthwise thereof, see Fig. 11, into which the threaded stem or shank 31 is screwed. For the purpose of locking these two arts so that they cannot be rotated relative y to each other I provide a spring clip or locking key 32 of the shape shown. This clip comprises' a coil portion -35 which encircles the shank 31 and two end portions 33, 34, which extend 4o lengthwise of the shank. The parts 33 and 34 lie in a slot which is in effect a key-slot 36, in the said shank- 31, and the ortion of the part 34 which rojects out of t e said slot is received in a s ot 37 on the inner face of the sleeve or body vportion 30. In this Way a slidable spline or key is provided. ABy slipping back this spline or key so that its lower vend-is clear of the portion 30, the parts 30 and V31 may b e turned relatively to each other thereby lengtheningvor shortening the shank of the hangpr, as will be clear. By this arrangement it Will also be clear that the base vided with two key locking slots 37 and 3S ninety degrees apart sothat after the shank member 31 has been screwed in far enough to the pipe or to a point in'alii-ie'tig'flit*anglesY with the axis of the pipe, and in doing so, the ,y

screw would be turned three-ei fhths of a revolution more or less after the 'angecame in contact with the ceiling, resulting in the wood about "t'h''els -w`v b'iiig'ovrstrained. With the double slot, the shank screw may be stopped on any quarter and still allow the iingers to assume their proper position in relation to the pipe. -The extra force required in this case would be so slight as to be of no importance. i
